On our '05, all I did related to performance was switched all fluids to AMSOIL (engine, tranny, f/r diffs, xfer case, ps, brakes) & added a drop-in filter. Ran really smooth after all that, plus it was my wife's and she didn't want me to go outrageous on it. Other non-perf mod I did was the Hi+Low+Fogs.

If you are wanting down low, I would recommend a cam and a blower.

You mean Cams 4.2 is dual over head cam and anyone know where to get some cams

Is yours a straight 5cyl?

You can take out the 4.2 and bolt in a 6.0L

I would just get it tuned and maybe an intake if they make one for the I6. STAY AWAY from programers. They are a waste of money.

This would definitely be your cheapest route.
